Output in Run-File
Contents
Output data of optimization problem in PSG Run-File environment are stored in txt files in the folder with the input data txt files with the results of optimization process.
Output files
solution_<problem name>.txt |
solution of the optimization problem ; |
point_<problem name>.txt |
optimal point of the optimization problem stored in General (Text) Format of PSG; |
log_<problem name>.txt |
information about the processes of solving the optimization problem; |
error_<problem name>.txt |
information about errors occurred during the solution of the optimization problem. |
Remarks
| • | File log_<problem name>.txt is optional and is generated only after marking field "Log File" in Run-File program. |
| • | File error_<problem name>.txt is optional and is generated only if errors were occurred. |
| • | If the name of problem is not present in the problem statement (Brief Description of Optimization Problem), than by default <problem name> is problem_1. |
Solution file
File solution_<problem name>.txt contains solution of the optimization problem with the following fields:
Problem |
status of solution of the optimization problem: optimal | feasible | infeasible | unbounded | calculated (for calculation problems); |
Timing |
working time of solver including: data loading time, preprocessing time, solving time; |
Variables |
values of variables of optimization problem: |
Objective |
value of the objective function in optimal point; |
Constraint |
value of the constraint function in optimal point and it's maximal deviation from specified in problem bounds (in square brackets); |
Function |
value of functions used in optimization problem formulation in optimal point. |
Example
This example uses CVaR minimization problem from section Quick Start with PSG Run-File. Input data for this problem are in folder ...\Aorda\PSG\Examples\Problems\Problem_CVaR\
PSG Run-File program creates and saves to this folder the following files:
solution_problem_cvar.txt |
solution of the optimization problem; |
point_problem_cvar.txt |
optimal point of the optimization problem; |
log_problem_cvar.txt |
log file for the optimization problem. |
To view the solution file solution_problem_cvar.txt click on the "Show" button of the "Solution File" field. After clicking on the "Show" button file is opened by the default text editor:
The point and log files are in the folder ...\Aorda\PSG\Examples\Problems\Problem_CVaR\:
